ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 478,263, dated July 5,1892. Application filed November 4, 1891. Serial No. 410,860. (Nomodel.)

To all whom it may concern:

Be it'known that I, JOHN R. MOSS, a citizen of the United States,residing at WVebster, inthe county of WVestmoreland and State of-Pennsylvania, have invented certain new and useful Improvements inElevators; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertainsto make and use the same.

This invention relates to elevators for hoisting building materialsinthe erection of buildings; and it consistsin certainimprovements in theconstruction of such apparatus, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a side view of anelevator provided with my improvements. Fig. 2 illustrates the device insectional front View. Fig. 3 represents an inclined way for the lowerend of the elevator. Fig. at illustrates the links and lifters.

On a shaft a, having its bearings in suitable frame work, are mountedtwo chainwheels A, and on a lower shaft b are two other chain-wheels A,the elevator consisting, mainly, of two endless chains B, passing aboutsaid wheels and connected at intervals by cross-bars to which aresecured lifting devices for carrying up bricks or other materials. Eachof the endless chains B is formed of links 0 and (1, arrangedalternately in the chain, the link 0 being oblong and square in form andthe link (Z being in the form of a plate, with its ends bent over towardeach other, so as to hook at either end to a link 0, as shown. Thechains B are connected by horizontal bars f, which are about one footapart, the ends of each of said bars extending into two links (I of thechains. The bars f are usually widened where they rest in links d, asseen at 6, so that they fit looselyin said links. The studs orprojections t' on bars f are to prevent said bars slipping endwise inthe links. Fastened to each of the barsfis a litter O, which is formedof a number of rods or hooks g, which are formed with angular bends andare suitably constructed to receive bricks. The hooks g are properlyspaced apart, so that each of the lifters will readily receive a singlebrick.

D indicates an inclined way mounted on' a frame at the lower end of theelevator and formed of parallel rods h, secured in a frame E, said rodsbeing inclined downward toward the elevator with their free ends nearthe vertical plane of the bars f, carried by the chains B. The rods hare so spaced apart that as the lifters O are raised by the elevator thehooks g of each lifter pass between the lower ends of said rods, so thata brick lying across said rods at their lower ends is caught by thelitter and carried up by the elevator. The lower ends of the rods h areturned up slightly, as seen at m, to stop the bricks sliding down theinclined wayD at the right point. At the top of the elevator anotherinclined way D is secured in position to receive the bricks from theelevator as the lifters pass over the upper chain-wheels and movedownward. The inclined way D is provided with parallel rods h, which areinclined downward from the elevator and properly spaced, so that theupper free ends of the rods are in position for the hooks of the liftersto pass between them as the lifters go downward after discharging theircontents to the inclined way D.

The shaftsof the chain-wheels may be rotated by anysuitable means, andthe links of the chains B being detachable the elevator may belengthened or shortened, as desired.

The bricks, being placed on the inclined way D, slide down the way tothe elevator, and the latter being in operation the lifters 0 each takea brick from the inclined way as they go upward. the upper chain-wheelsand commence their downward movement they discharge their contents tothe upper; inclined way D, and the bricks slide down'the latter from theelevator.

I claim- An elevator having a double chain with connecting cross-barsfand oblong links at right angles to each other, the said cross-bars fbeing provided with hook-rods and end studs, substantially as shown, andfor the purpose specified.

In testimony whereof I have affixed my signature in presence-of twowitnesses.
